The earliest automatic movements from Eterna were advertised simply as Eterna Automatic. It was not until 1948 when a line of watches for ladies used the Eterna-Matic name. The term would later be used for many other movements for ladies and men. Although somewhat related, there were many differences between the various movements that used this name.
Early Eterna Bumper Movements
Eterna's first automatic movement was Cal. 835 in 1939. This 12.5 ligne movement featured small seconds. Between 1940 and 1945, Eterna introduced more movements, all with bumpers rather than free-rotating mass. These were not Eterna-Matic branded.
- Cal. 833 - 12.5 ligne, central seconds
- Cal. 834 - 12.5 ligne, small seconds
- Cal. 1033 - 9.5 ligne, no seconds
- Cal. 1034 - 9.5 ligne, central seconds
- Cal. 1158 - 12 ligne, central seconds
- Cal. 1159 - 13 ligne, central seconds
- Cal. 1176 - 13 ligne, small seconds
All of these movements were abandoned after 1948 as Eterna had developed a new movement with a central rotating mass mounted on ball bearings.
Eterna-Matic for Ladies
The first Eterna-Matic movements appeared in 1948 or 1949. These were compact (9.25 to 10 ligne) movements for ladies watches and were the first to leverage the ball-bearing rotor which would become the trademark of Eterna. Both movements had direct central seconds.
- Cal. 1198 - 9.25 ligne (20.50 mm) diameter, 5.35 mm thick, replaced by Cal 1319
- Cal. 1199 - 10 ligne (22.10 mm) diameter, 5.35 mm thick, replaced by Cal 1321
Smaller models with direct central seconds were soon introduced:
- Cal. 1194 - 7.75 ligne (17.20 mm) diameter, 5.35 mm thick
- Cal. 1195 - 8.25 ligne (18.30 mm) diameter, 5.35 mm thick
Larger models followed by 1950:
- Cal. 1237 - 12.5 ligne (27.60 mm) diameter, 5.90 mm thick, central seconds, date window
- Cal. 1239 - 13 ligne (29.00 mm) diameter, 5.90 mm thick, central seconds, date window
- Cal. 1247 - 12.5 ligne (27.60 mm) diameter, 5.90 mm thick, central seconds
- Cal. 1248 - 11.5 ligne (25.60 mm) diameter, 5.90 mm thick, central seconds
- Cal. 1249 - 13 ligne (29.00 mm) diameter, 5.90 mm thick, central seconds
The original compact movements were replaced by 1953, with many similarities to the Cal. 12xx series:
- Cal. 1319 - 9.25 ligne (20.50 mm) diameter, 5.60 mm thick, central seconds
- Cal. 1321 - 10.5 ligne (23.30 mm) diameter, 5.60 mm thick, central seconds
